ADJUSTABLE "l3 iii-BLANK MACHINE.

To all whom it may concern:

Be it known that 1, WILLIAM P. Huang, a citizen of the United States of America,

and resident of Chicago, Cook county, Tlli-. 5 nois, have invented a certain new and use- '10 making (flQilt-llllfOlCBd and wire-bound box blanks. It relates more particularly. to machinery for this purpose in which an end less chain work-holder is employed for holding the cleats and veneer in place and passing the same below the staplers to secure the binding wires in place. Such a machine is shown in United States Patent No. 815,197, issued March 13, 1906, and in United States Patent-No. 864,955, issued September 3, 1907. I do not, however, limit myself to this particular kind of machine.

The object of my invention is to provide improved means for varying the distance between the spacing blocks on the workholder of a machine of this general character. It contemplates, therefore, a set of spacing blocks which can be readily lifted out of the work-holder, without disturbing the parts of the latter. and then re-inserted in different positions, thus changing the distance between them to accommodate cleats of different lengths. It also contemplates an .endless chain work-holder in which the spacing blocks are adjustable or readily movable to different positions thereon without loosening the bolts of the chains. Heretofore, the adjustment of the spacing blocks on the chains necessitated loosening of the bolts which hold the links together, which made it necessary to lose some time in changing the work-holder for a longer or shorter box blank. lVith my improvement, however, this operation of changing the machine for -a different size of box is very much facilitated. The change is made easily and quickly and without interrupting the operation of the machine for an objectionable period of time.

In the accompanying drawingsFigure 1 is a perspective of a portion of one of the chains of the work-holder shown in said prior Patent #864,955, illustrating adjustable spacing blocks therefor embodying the principles of my invention. Fig. 2 is a perspective of one of the spacing blocks shifted to their required positions.

shown in Fig. 1. Fig. 3 is a perspective of the wedge that holds the spacing block in place, and that serves to separate or space the edges of the veneer. Fig. i is a plan of a portion of the chain shown in Fig. 1. Fig. 5 is a cross section on line Fig. 6 is a view similar to Fig. 5, showing a diflerent form of my invention. Fig. 7 is a view similar to Fig. at, showing another form of ment, however, the inner surfaces of the 7 pockets have vertical grooves c. The blocks D each have a rib (Z on one side and a groove (Z on the other side. A wedge or key 0Z is adapted to be inserted in the groove (Z, and in one of the grooves c, as shown. The rib (Z then engages a groove 0 atthe other side, and the block is thus held in place. The wedge or key (Z serves, also, as a means for spacing or separating the edges of the veneer. Should it be desired to change the distance between the blocks D, to accommodate cleats of a different length, the wedges or keys (Z are removed and the blocks are Thus the work-holder is changed without loosening the bolts B, and in a comparatively short time. i

In Fig. 6 the construction is very much the same, except that the block E is provided with spring actuated members 6-6 for engaging the grooves c in the pocket. By movin g these members together, the same can be disengaged from the said grooves, and the blocks therebyrelnoved upwardly from the pockets. The arrangement is preferably such that the members 0 hold the blocks securely in place while the chain travels upside down.

In Fig. 7 the block F is very much like the block D, except that it is provided with ribs f at each side thereof. These ribs engage the grooves at each side of the pockets with sufficient friction to hold them in place while the chain is traveling upside down.

The member 6 on block E, and the lug f on the block F, serve to separate or space the edges of the veneer.

- It'will be seen that with either form of my invention the spacing blocks are easily and quickly shifted to new positions without the necessity of loosening the bolts B. In each case the block can be lifted directly upward out of the pocket, and then inserted downward at another point therein. This greatly facilitates the changing of theworkholder for different lengths of cleat. The blocks can be used in any suitable form of Work-holder. In any event, however, the devices 03 or e or f, or any suitable means, engage the teeth to hold the blocks in different positions.

When a block falls at the juncture between two pockets, I then use a split or divided block, held part on one pocket and part on the other, by any of the expedients shown for this purpose, in a manner that Will be readily understood. The blocks shown can be used on dilferont chains or all on the same chain.

What I claim as my invention is:

1. A box blank machine comprising a traveling Work-holder, a row of spacing blocks on said work-holder, and means for holding said blocks a variable distance apart, said means being fixed on said workholder, each block having a vertical groove, and a device insertible in said groove and engaging said means.

2. A box blank machine comprising a traveling Work-holder, a row of spacing blocks on said Work-holder, and means for holding said blocks a variable distance apart, said means being fixed on said workholder, each block having a movable element at the side thereof for engaging said means.

3. A box blank machine comprising a traveling Work-holder, a row' of spacing blocks on said work-holder, and means for holding said blocks a variable distance apart, said means being fixed on said workholder, each block having a vertical groove, and a, device insertible in said groove and engaging said means, said Work-holder consisting of links and bolts which are not disturbed by the said adjustment of said blocks.

4:. A box blank machine comprising a traveling work-holder, a row of spacing blocks on said work-holder, and means for holding said blocks a variable distance apart, said means being fixed' on said workholder, each block having a movable element at the side thereof for engaging said means,'said work holder having links and bolts which are not disturbed by said adjustment of said blocks.

5. A box blank machine comprising a traveling Work-holder, a row of spacing blocks on said Work-holder, and means for holding said blocks a variable distance apart, said means being fixed on said Workholder, each block having a vertical groove, and a device insertible in said groove and engaging said means, said means-consisting of a side Wall having teeth thereon to hold the blocks in different positions.

6. A box blank machine comprising a traveling Work-holder, a row of spacing blocks on said work-holder, and means for holding said blocks a variable distance apart, said means being fixed on said Workholder, each block having a movable element at the side thereof for engaging said means, said means consisting of a side wall having teeth thereon to hold the blocks in different positions.

7. A box blank machine comprising a traveling work-holder, a row of spacing blocks on said Work-holder, and means for holding said blocks a variable distance apart, said means being fixed on said workholder, each block having a device at the side thereof for engaging said means.
